OS X 10.10.2 will fix years-old Thunderbolt hardware vulnerability: "The so-called 'Thunderstrike' hardware exploit was publicized late last year, but the hack takes advantage of a flaw in the Thunderbolt Option ROM first disclosed in 2012. Until now, that flaw hasn't been patched, but according to iMore, the latest beta of Apple's OS X 10.10.2 update fixes the problem."
